Ebay Description:
The Yamaha CS-15 is a 37 key, monophonic analog synthesizer, featuring dual signal paths (oscillator/filter/amp), an LFO (saw:down, sine, S/H waveforms), 2 envelopes (ADSR), external filter input, and CV/gate IO. Each signal path features an oscillator (saw and pulse waveforms) with FM and portamento, noise, and resonant low|high|band pass filter.
